You have to put a film, ah......The focus is not on metal The focus of the mobile phone screen where the metal grinds the glass is dust This problem is purely a matter of the hardness of the material, the Mohs hardness of the glass is average, and the hardness of the stainless steel mode is generally taken, so you can put things like keys on the mobile phone screen and scratch hard, except that it may scratch the plastic of the fuselage, the screen has nothing at all. But if you get dust on your phone, it will be a tragedy if you gently brush it with your hand. Some friends said they didn't believe it@amitabhapro or they thought it was harmless, but you could try to take a handful of sand and sprinkle it on the glass and touch it with your hands, and it would be fun.

The sand grains are mainly quartz grains, and the hardness of quartz is about 7, which completely kills glass. A lot of the dust in the air is so tiny that it can be suspended in the moving air – think of a sandstorm, but it's not so exaggerated. As for rubbing the abrasive belt into your pocket or the next time you touch the screen, you will be very hurt.

For example, the computer that posted now has a ...... screen that has been worn outBecause in Xinjiang, because of the dust and sand that falls every day, the screen has a little static electricity, and the adsorption is strong, and every time I wipe it, it hurts a little bit. Fortunately, the laptop screen is used at a distance of about 40 cm, and you can't see it - what about a mobile phone that is within 10 cm of your eyes at every turn? View the original post

It is necessary, even Corning's glass, the hardness is Mohs hardness), the general knife is, as for the key made of copper or something, it is even smaller, and these really can't cause scratches on the touch screen. But in case the phone accidentally falls to the ground, it's different, the main component of sand is quartz, the hardness reaches 7, you can easily leave a gorgeous scratch on the screen, even if you take good care, usually there will be some fine sand and dust in people's pockets, and it will scratch the screen sooner or later.

It is necessary to apply film to mobile phones, mainly for the following reasons: to prevent screen scratches and abrasions, to prevent fingerprints and stains, to prevent glare and reflections, to prevent mobile phones from self-detonation, and to protect personal privacy.

1. Prevent screen scratches and abrasion: The film can effectively protect the mobile phone screen from scratches and wear, thereby prolonging the service life of the mobile phone screen.

2. Prevent fingerprints and stains: The mobile phone screen is easy to be stained with fingerprints and stains, and the film can block these stains and make the screen clearer.

3. Prevent glare and reflection: The film can also reduce the reflection and glare of the mobile phone screen, making the screen more respectful and legible.

4. Prevent the self-explosion of the mobile phone: the use of low-quality or unsafe mobile phone chargers will lead to hidden dangers such as overheating and short circuit of the mobile phone. Some explosion-proof films can also effectively block the radiation and electromagnetic waves emitted by mobile phones.

5. Protect personal privacy: Some special anti-privacy films can also effectively prevent others from observing your screen and peeping into your personal privacy.

The mobile phone does not need a film, and the mobile phone can be used normally without a film.

The mobile phone does not need a film, and the mobile phone can be used normally without a film.

The use of the mobile phone without film does not affect the use. However, the film can effectively avoid some sharp objects from causing direct damage to the screen, and you can choose whether to apply the film according to your personal preference. The mobile phone screen is not filmed, and it is easy to scratch the screen during use, which will affect the appearance.

If the explosion-proof film is not pasted, the screen will easily break if the mobile phone is accidentally bumped or dropped, which will not only affect the appearance, but also affect the normal use if it is seriously broken. For those who cherish their mobile phones, it is recommended that they should put on explosion-proof film, so that even if the mobile phone is accidentally hit violently, the damage can be minimized. If the film is not applied for a long time, the oleophobic layer on the mobile phone screen may also be depleted and polished.

Of course, it is a bit serious to say that it is exhausted, but it will have some effect. Just imagine,Let the screen run naked for a long time,After the oleophobic layer on the surface is slowly worn off,The screen loses its good anti-grease function,You dot and scratch on the screen every day,All kinds of fingerprints are printed,It's hard to clean up,It's not uncomfortable to watch? OCD is simply unbearable.

The film can also protect the mobile phone screen to a certain extent and prevent falling. Don't underestimate this film, although the film cannot guarantee that the screen will not be broken if the phone is dropped, but if you don't stick the film, the probability of the screen breaking will definitely be higher. Think about how expensive it is to change the screen of a mobile phone now, especially the screen of a curved screen mobile phone** is higher, so it is not cheap to change the screen, and we still have to take more care of the new machine.

Except, of course, local tyrants. So back to the question we asked at the beginning, is there a need for a film on the phone. It will make the mobile phone screen flowery, which is not beautiful.

If the mobile phone screen is spent, changing the screen may cause the touch of the mobile phone to be insensitive, and the film will not make the mobile phone screen flowery, and the screen can be changed at any time, and it will also protect the mobile phone screen and prevent cracks.

It is necessary that there will always be accidentally touching the phone screen. Affixed for protection.

If you are using a vivo mobile phone, in order to pursue a better hand experience, the screen can be removed without a film, and the included film can also be removed; However, the screen has a film to better protect the screen and prevent scratches, so it is recommended to put a dust-attacking protective film.

There is still a certain need for mobile phone film. The film can reduce the probability of accidental wear and tear of the mobile phone screen to a certain extent, but it cannot reduce the probability of broken screen, which can be said to be negligible. There is also an important aspect, psychological satisfaction, the film can rest assured and obtain psychological satisfaction.

Bare metal use. It will make the phone have a lot of small scratches. Some people with OCD can be unbearable.

Of course, you can also determine whether to apply film according to the price of your mobile phone and the frequency of changing your mobile phone. If the mobile phone is not expensive and the frequency of changing the mobile phone is high, it is better to use the bare metal. However, the mobile phone is expensive and there is no idea of changing the mobile phone in a short time, so it is better to use the film tape sleeve.
